Right hand propellers

Right hand propellers

Hello, I have made some of this pumps mods.
I live in Argentina and here we have 220v 50hz, I do not known why but if you start pump here the 99% of the time it starts spinning on the right.
I want to ask If there are props like the dummas 3004 that are right hand.
I can see that If use a right hand proppeller I can solve the problem of start clokwise...
thanks

You have to put in a stopper for the impeller to hit when it turns backwards in order to correct it.

The idea is that when the prop turn in the wrong direction, the flow of the water makes the proppeller move and hits the stopper?
How many milimeters do you put the stopper from the prop?
thanks

1/8" to 1/4" will be fine.

Bigger props

Hello I have made with similar maxijet 1200 pumps and using octura 3004 and the flow are great.
I have mode also a 450gph pump and there seem no diference with the 280gph models.
One pump uses 13w and the biger pump use 26w.
Is there a bigger propeller to use in bigger pumps?
Anybody know where to buy?
thanks

An additional alternative to an aluminum rod is a 2.4mm ceramic rod, which may be hard to find. However, maybe someone out there knows of a supplier?

I'd like a bit of compairison. I don't remember where I saw the mod, but here's what I did. Take a MJ1200, hack off the exit spout, and drill holes around the bottom. This allows less restriction and more water in the intake. How does this compare? Is it still dramatically less than this mod?

That takes a MJ1200 from 296gph to maybe 350gph with wider flow.


Throwing a Dumas 3004 on it will take it up above 2000gph.

I just got mine from MJmods. Works wonderfully, really its way to much flow I put it behind my rocks and i'm going to get another one and slap it on a smaller pump and put two of them in there. I thought about building my own but I have to many things going on to worry about it.

All he had to do was refund me my money for a kit I never received or send me the kit I paid for. I would not of aired this dirty laundry like this if he just took care of it.
I paid 16 dollars for a kit and didn't receive that kit. So somewhere in translation it ended up that I would need to meet with his father for me refund. No thanks, keep the 16 bucks. Heres your press for ya.
